Description
Technical Field
The invention relates to the field of slope monitoring, in particular to a slope locking section intelligent positioning and feature identification method
Background
Landslides, as a typical disastrous geological disaster, cause enormous economic loss and casualties on a global scale, thus leading to extensive research. However, due to the complexity of the landslide mechanism, the evolution of landslide is not yet fully understood. Due to the huge potential energy of the large-scale rocky landslide, a chain-type geological disaster with high speed, long distance and integration of 'collapse → slide → flow' is formed after the large-scale rocky landslide is separated from mother rocks, and destructive damage and serious casualties are often caused. The rock landslide relates to different geological environment conditions and geological structures, has different inducing mechanisms and triggering factors, and has extremely complex deformation, destruction and evolution mechanisms and generation processes. The locking section plays a key role in the sliding process of the rock slope, the locking section refers to a part which is not communicated on a sliding surface, bears stress concentration and provides a key bearing effect in the slope instability process, and the strength and deformation of the part determine the integral stability of the slope. Slopes can be classified into two broad categories, locked slopes and unlocked slopes, based on the presence or absence of a locking segment that controls the stability of the slope. It is emphasized that the locking segment has an energy-gathering effect, which stores a large amount of elastic strain energy before the locking segment is not penetrated through, and converts the elastic strain energy into slope kinetic energy when the locking segment is suddenly broken, resulting in high-speed starting of the landslide, so that the locking type slope is often strongly destructive after instability, and typical examples are extra-large landslide of showa shinkangtai village, mountains of shanghai, mountains of Chongqing Wulong mountains of cocktail landslide and the like. The slope of the locking section exists in the weak layer, if the through destruction does not occur in the locking section on the latent sliding surface, even if the slope creeps to slide under the action of factors such as rainfall and the like and the acceleration behavior occurs, the integral instability sliding cannot occur, and the locking section has obvious characteristics, so that the locking type slope is probably one of the global problems of slope instability prediction, namely that the strength is relatively weak and the most possibility is broken through firstly. In the research on the locking type side slope, the current means is mainly to carry out inversion analysis on the landslide process of the side slope according to geological data after landslide, and a method for finding the position and the characteristics of a locking section before landslide is lacked. Due to the lack of exact information of the locking section before design and construction, the stability design and construction of the side slope are influenced obviously. Therefore, the slope locking section intelligent positioning and feature identification method provided by the invention is very necessary.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a slope locking section intelligent positioning and feature recognition method. The method can solve the engineering problem that the position and the characteristic information of the positioning and locking section cannot be accurately judged at present, makes up the defects of conventional design of the side slope, and can more reasonably and accurately analyze the stability of the side slope and beneficially guide the design, monitoring and construction processes of the side slope.
In order to solve the technical problems, the invention is realized by the following technical scheme:
a slope locking section intelligent positioning and feature recognition method comprises the following steps:
step (1) installation and automatic monitoring of large-scale micro-seismic monitoring system
And (3) defining a side slope monitoring range according to the side slope geological data and the engineering construction requirement, and dividing the side slope in the range to be monitored into different grids according to the elevation and the transverse and longitudinal spacing. And a guided wave rod is installed in the middle of the divided grids through drilling, and a micro-seismic automatic monitoring probe is installed at a port above the guided wave rod. The automatic micro-seismic monitoring probe comprises a sensor, wireless transmission equipment, a solar cell panel, a storage battery, a protective box body and the like. Microseismic event data generated when external factors such as rainfall, earthquake, construction and the like change are collected by the automatic monitoring probe and remotely transmitted to the data processing center.
Step (2) automatic processing of microseismic monitoring data and primary identification of position of locking segment
Because the locking section has higher strength, a large amount of elastic strain energy is gathered at the locking section, the locking section can be more strongly damaged in the process of external disturbance of the slope, and the energy can be released outwards in the form of waves. Waves caused by the same microseismic event are received by a plurality of monitoring probes at different positions and buried depths and then are remotely transmitted to a data center. The data center effectively eliminates external interference data from the received real-time micro-seismic monitoring data by adopting an artificial intelligence method, and keeps the micro-seismic monitoring result generated by deformation and damage of the rock mass. The location of the microseismic event and the energy concentration zone can be determined via a double-differenced localization algorithm to make a preliminary determination of the locking segment location.
Step (3) accurate positioning and feature recognition of locking section
And (3) on the basis of the primary positioning position of the locking section in the step (2), reducing the microseismic monitoring range, subdividing the obtained energy gathering area into different grids, repeating the installation process of the microseismic monitoring system in the step (1), and installing automatic monitoring probes at different burial depth positions in the range of the energy gathering area defined in the step (2). Microseismic monitoring is again performed on this region. And then the obtained monitoring data is processed again to obtain more detailed information such as the position, the size and the like of the locking section. Through comparing the microseismic data information of different rock masses in the database, other dimension information of the locking section can be obtained. Compared with the prior art, the invention has the following advantages:
through the micro-seismic data monitoring probe of intelligence, can be long-rangely monitor the side slope. Adopt solar cell panel to provide the energy for probe and transmission equipment, high-efficient environmental protection has avoided the destruction of transmission optical cable because of construction and external reason cause simultaneously, reduces labour cost and transmission optical cable expense, saves the investment. The artificial intelligence technology is adopted to process the monitoring data, and the slope monitoring data can be efficiently picked up. Adopt many rounds of location, can carry out accurate location to the locking section. Through the accurate positioning analysis to the locking section, can provide favorable direction for design construction monitoring, ensure the stability and the safety of side slope.
